Post-surgical US examinations were performed using a standardized approach at both institutions, first assessing the muscles supplied by the median nerve (MN) and then conducting a detailed evaluation of the MN course at the wrist. To avoid misinterpreting ligament regrowth, patients with recurrent symptoms two months or later after surgery were excluded. Only cases showing clear compression by the TCL were selected.Results: A total of 46 patients were identified with incomplete release of the TCL, with the average uncut portion of the ligament measuring 6.7 mm. The proximal margin of the TCL was incompletely released in 65% of the cases, while the distal margin was affected in 35%. Symptoms in these patients persisted after surgery, and, in 52%, they were worse than before surgery. A reduction in thenar muscle bulk was observed in 37 patients. Follow-up clinical data were available in eight patients, with three undergoing US evaluation after revision surgery.Conclusion: US can effectively demonstrate the incomplete release of the TCL, visualized as a fibrillar uncut structure compressing the MN and producing an hourglass appearance of the nerve. In addition, US may help detect other factors that contribute to persistent symptoms and help to guide revision surgery.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"284-293"},"PeriodicalIF":2.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145985779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nodules were divided into benign and malignant. B-mode US evaluated echogenicity, composition, dimensions, contours, limits, and presence of halo and echogenic foci. Elastography classified nodules from I (completely softened) to IV (completely hard). The mean nodule deformation value (assessed in m/s and kPa), the deformation ratio between nodule and thyroid parenchyma (TDR), and the deformation ratio between nodule and pre-thyroid musculature (MDR) were calculated.Results: The significant univariate parameters for B-mode were hypoechogenicity, halo, microcalcifications, irregular contours, and ill-defined limits. All parameters were significant for elastography. The MDR (in kPa) was the best elastographic parameter: nodules with MDRs> 1.53 exhibited a higher chance of malignancy (AUC-ROC=0.831). B-mode ACR-TIRADS had an AUC of 0.678; 95% CI: 0.596-0.760, while ATA had an AUC of 0.680; 95%: 0.597-0.763.

While several testing methods exist, their availability and adoption remains varied, and the frequency of testing is often insufficient. Here we aimed to conduct a user-driven simple and rapid probe quality testing approach and to evaluate its rationale.Materials and methods: Testing was based on physical examination of probe integrity (all probes) and in-air reverberation check (for curvilinear and linear array probes), findings, as well as probe age were registered. Prior to assessment, probes were divided into a high-risk vs. a low-risk category, based on the perceived risk of probe damage as a result of the typical application (e.g., non-invasive vs. interventional, inpatient vs. point-of-care).Results: 17.4% of the low-risk and 31.4% of high-risk probes demonstrated physical wear or damage. Reverberation artifacts were significantly more frequent (68%) in the high-risk category vs. the low-risk one (29.4%). Probes with either physical or reverberation faults were significantly older on average.Conclusion: The simple, rapid investigational technique uncovered an alarming percentage of probe damage or faults. It also identified immediately solvable technical issues (e.g., poor cable contact mimicking dropout). High-risk probe usage resulted in an increased rate of reverberation errors and physical damage. Risk-based, frequent rapid observational testing of ultrasound probes could substantially improve both diagnostic quality and patient safety.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"294-299"},"PeriodicalIF":2.9,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142591963","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous follow-up examinations and invasive diagnostic procedures, such as fine-needle aspiration, fine-needle biopsies, and thyroidectomies, are performed, leading to potentially costly and time-consuming diagnostic procedures and overtreatment. Most experts and scientific societies (EFSUMB, WFUMB, etc.) encourage the use of multiparametric ultrasound evaluation (MPUS) to improve thyroid nodule characterization due to the continuous technological developments including new ultrasound software (microvascular flow imaging, elastosonography, etc.), contrast media (CEUS), and artificial intelligence (AI). Therefore, the recognition and proper use of new multiparametric ultrasound features of thyroid nodules are essential for minimizing unnecessary interventions and guiding appropriate treatment. The goal of these guidelines is to help initiate use of these features in routine clinical practice. In addition, we analyze the use of MPUS in some emblematic thyroid scenarios, such as cytologically indeterminate nodules, multinodular goiters, and extrathyroidal extension of the malignant nodule, and the usefulness of MPUS as a guide for thyroid biopsy/aspiration and in the staging of cervical lymph nodes. Recommendations based on the level of evidence of the published literature and on the EFSUMB expert group's consensus are given for each question.","PeriodicalId":49400,"journal":{"name":"Ultraschall in Der Medizin","volume":" ","pages":"253-262"},"PeriodicalIF":3.2,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145662469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aim of this study was to investigate whether wall layer data measured on gastrointestinal ultrasound could predict endoscopic activity in CD.Materials and methods: 64 CD patients underwent a gastrointestinal ultrasound examination and endoscopy ± 2 weeks apart in a single-center prospective study. Bowel wall thickness and the thickness of individual wall layers corresponding to the mucosa, submucosa and the proper muscle wall were measured and compared with the simple endoscopic score of Crohn's disease (SES-CD) in the most affected bowel segment where SES-CD >2 was defined as activity.Results: There was increased absolute thickness of the mucosa (1.8 versus 1.1mm, p =0.001), submucosa (2.8 versus 1.2mm, p <0.001), and proper muscle (1.6 versus 1.1mm, p =0.006) in patients with endoscopic activity. After an ROC analysis, Youden's index suggested a 1.8 mm cut-off for submucosal thickness and disease activity resulting in a sensitivity of 90%, specificity of 78.3%, and accuracy of 84.9%. In contrast, a bowel wall thickness of 3 mm had a sensitivity of 97.3%, specificity of 52.0%, and accuracy of 79.0%. The submucosa was also relatively thicker (0.45 versus 0.36, p=0.008), while the proper muscle was relatively thinner (0.25 versus 0.34, p=0.001) in endoscopic activity.Conclusion: Patients with Crohn's disease and endoscopic activity had an increased thickness of all bowel wall layers in affected areas.
